Two new flavonoids, wushanicaritin (1) and wushankaempferol (2), along with 24 known flavonoids were isolated from the whole herb of Epimedium wushanense T.S. Ying (Berberidaceae). On the basis of NMR and ESI-MS spectroscopic analysis, structures of compounds 1 and 2 were elucidated as 8-γ-hydroxy-γ,γ-dimethylpropyl-3,5,7-trihydroxy-4'- methoxyflavone and kaempferol 3-O-α-l-[2,3-di-O-β-D-(6-E-p-coumaroyl) glucopyranosyl]-rhamnopyranosyl-7-O-α-L-rhamnopyranoside, respectively. DPPH radical… Expand
A new flavonol glycoside from the aerial parts of Epimedium koreanum Nakai
TLDR
A new prenylated flavonol glycoside was isolated from a 95% methanol extract of the dried and powdered aerial parts of Epimedium koreanum Nakai, along with seven previously known flavonoids, and the antioxidant activities of these compounds were determined by the DPPH free radical scavenging assay. Expand
Anti-radical flavonol glycosides from the aerial parts of Cleome chelidonii L.f.
TLDR
The DPPH radical scavenging properties of the flavonoid glycosides were studied in order to appreciate the effect of the glycoside parts and of the ester groups on this activity compared with the quercetin and kaempferol aglycones. Expand
Flavonoids from Epimedium pubescens: extraction and mechanism, antioxidant capacity and effects on CAT and GSH-Px of Drosophila melanogaster
TLDR
Flavonoids of E. pubescens showed great potential for becoming a natural antioxidant because of their antiradical ability and effects on CAT and GSH-Px of the model organism. Expand
Flavonoid glycosides isolated from Epimedium brevicornum and their estrogen biosynthesis-promoting effects
TLDR
The results suggested that the isoprenylated flavonoids from E. brevicornum may produce beneficial health effects through the promotion of estrogen biosynthesis, and PDE5 warrants further investigation as a new therapeutic target for testosterone biosynthesis in the prevention and treatment of estrogen-deficiency related diseases.

Evaluation and prediction of the antioxidant activity of Epimedium from multi-wavelength chromatographic fingerprints and chemometrics
Epimedium herbs are commonly used as herbal medicine ingredients in China. In this study, firstly the total phenolic content and total flavonoid content (TFC) of Epimedium extracts were determined,Expand
Extraction, antioxidant and antimicrobial activities of Epimedium acuminatum Franch. polysaccharide.
TLDR
Polysaccharides from Epimedium acuminatum were extracted by hot water and optimized with response surface methodology, and EAP60-1 with molecular weight of 114,667 Da was found to exhibit significant antihemolytic activity and antimicrobial activity. Expand
2-Phenoxychromones and prenylflavonoids from Epimedium koreanum and their inhibitory effects on LPS-induced nitric oxide and interleukin-1β production.
Two new 2-phenoxychromones 1 and 2 and two prenylflavonoids 3 and 4 along with 12 known compounds (5-16) were isolated from the CH2Cl2-soluble fraction of a methanol extract of Epimedium koreanum.Expand
Chemical constituents from Epimedium koreanum Nakai and their chemotaxonomic significance
TLDR
This is the first report of compounds 2, 3, 4 and 9 in E. koreanum and of compounds 5 and 7 in the family Berberidaceae and the chemotaxonomic significance of the isolated compounds is discussed. Expand
Chemical Constituents, Quality Control, and Bioactivity of Epimedii Folium (Yinyanghuo).

[Comparison of antioxidative and antitumor activities of six flavonoids from Epimedium koreanum].
TLDR
The antitumor activity of E. koreanum may be partially related to the antioxidantive activity of flavonoids, and compounds I, II, V and VI could inhibit the proliferation of MCF-7 and HepG2 in dose-dependant manner, but compounds III and IV had no effect on the proliferation. Expand
